  • Patent number: 6424070
    Abstract: The invention is directed to an improved limited torque motor (15). In the preferred embodiment, the motor comprises a magnetized rotor (16) mounted for rotational movement relative to a stator (18), the rotor and stator being elongated about an axis x-x, and the stator having coils (19) adapted to be selectively energized by a current to exert a torque on the rotor, and the stator having a centering magnetic configuration (20) at a first axial location (21) and arranged to produce a torque on the rotor as a function of rotor angular displacement (A), and the stator having a driving magnetic configuration (23) at a second axial location (24) and arranged to produce a torque on the rotor as a function of the current. The stator may comprise multiple radial pole pieces (35) and the coil may be wrapped around each of the pole pieces. The centering magnetic configuration may have less pole-pieces than the driving magnetic configuration. The rotor may have a constant magnetic configuration along its axis.
